Archer: if a sequence is unbounded, then i can say it's not periodic?
Firzen: if it was it was bounded
Archer: i've never studied this shit before
Archer: lol
Uberdude: -infinity, + infinity, -infinity, +infinity, ...
Firzen: because infinity is a number...
Uberdude: that sequence is unbounded, by the definition of bounded i am familiar with
Archer: "billywoods: if the period is M, then a{n} = a{n+M}, but a{n+1} =/= a{n+M+1}, contradiction"
billywoods: that is not a sequence of numbers, andrew :P
Archer: wow, i wish i could have thought this on the exam
Uberdude: sure it is
Firzen: when did infinity become a number again?
tywin: It may be unbounded, but it is not a sequence.
Uberdude: slighty after 0 became a number
tywin: Forget the infinities, I want to see infinitesimals become numbers again.
billywoods: lot of non-standard analysis done with infinitesimals
billywoods: all seems a bit silly to me, but then i've never looked into it, maybe it's not
Firzen: well infinity is at least not in R
Uberdude: neither is i
Uberdude: and i is a perfectly cromulent number
Firzen: so if infinity is a number, can you build an abelian group from a base set that has infinity in it?
Uberdude: nope, i build hotels
